Description: Gemcitabine HCl (formerly also known as LY-188011, NSC-613327; dFdC; dFdCyd; trade name: Gemzar), the hydrochloride salt of gemcitabine which is an antimetabolite anticancer drug, is a potent DNA synthesis inhibitor approved for cancer treatment. It inhibits DNA synthesis with IC50s of 50 nM, 40 nM, 18 nM and 12 nM in PANC1, MIAPaCa2, BxPC3 and Capan2 cells, respectively. Gemcitabine is converted intracellularly to the active metabolites difluorodeoxycytidine di- and triphosphate (dFdCDP, dFdCTP). dFdCDP inhibits ribonucleotide reductase, thereby decreasing the deoxynucleotide pool available for DNA synthesis.

In vitro activity: Gemcitabine induced NF-κB activity in BxPC-3, PANC-1, and MIA PaCa-2 cells and decreased the level of the NF-κB inhibitor IκBα in BxPC-3 and PANC-1 cells. Treatment of BxPC-3 cells with low dose Gemcitabine for 48 hours results in a dose-dependent increase in NF-κB binding. In contrast, NF-κB DNA binding is decreased in BxPC-3 cells treated with the higher Gemcitabine doses for 48 h; however, 24-h treatment with these higher doses increases NF-κB binding in BxPC-3 cells.
Cell Assay: BxPC-3, MIA PaCa-2, and PANC-1 cells are seeded in a 96-well plate. After 24 hours, cells are treated with vehicle, DMAPT and/or Gemcitabine for an additional 24 hours or 48 hours. Apoptosis is quantified using the Cell Death Detection ELISA to detect the amount of cytoplasmic histone-associated DNA fragments and expressed relative to vehicle-treated cells.
